I'm sure there are many ways to skin this cat but I just stumbled on this way. I had some leftover residue polish on the Trans Am and it wouldn't come off with clay bar, soap or a hard scrub. I read about vinyl cleaner doing the trick and already had some Armor All wipes in the arsenal so gave it a shot. And it worked flawlessly. Might not be anything new but it's new to me damnit and it works.
